PITTSBURGH — The Pittsburgh Penguins placed defenseman Kris Letang and goalie Tomas Vokoun on the injured list and sent forward Beau Bennett to the minors on Monday.

Letang will be out at least until Friday with what coach Dan Bylsma called a lower-body injury. Vokoun is out indefinitely due to blood clots discovered in his pelvic region two weeks ago.

Bennett, who impressed Bylsma during the preseason, was sent to Wheeling of the ECHL. He will likely be recalled to Pittsburgh before the season opener against New Jersey on Thursday.
